((x-2)^2)/(64)+((y+4)^2)/(16)=1

Lösung

\frac{( x - 2 ) ^{2}}{64} + \frac{( y + 4 ) ^{2}}{16} = 1

(h, k) = (2, - 4), a = 8, b = 4

Schritte zur Lösung

\frac{( x - 2 ) ^{2}}{64} + \frac{( y + 4 ) ^{2}}{16} = 1

Rewrite

\frac{( x - 2 ) ^{2}}{64} + \frac{( y + 4 ) ^{2}}{16} = 1

in the form of the standard ellipse equation

\frac{( x - 2 ) ^{2}}{8 ^{2}} + \frac{( y - ( - 4 ) ) ^{2}}{4 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (2, - 4), a = 8, b = 4

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (2, - 4), a = 8, b = 4

25 x^{2} + 16 y^{2} - 250 x - 32 y + 241 = 0

9 x^{2} + 5 y^{2} = 45

\frac{( x - 1 ) ^{2}}{9} + \frac{( y - 2 ) ^{2}}{4} = 1

25 x^{2} + 12 y^{2} + 20 x - 12 y = 4

9 x^{2} + 4 y^{2} - 18 x + 24 y + 9 = 0
